, This invention relates to improvements in dump cars. I

An obj ectof the invention is to provide, in a dump car, an improveddoor construction to be used in connection with Ingoldsby type of doorsupporting latches.

A specific object of the invention is the provision of an improved doorbeam extension adapted to be engaged by a locking latch pivotallymounted on the body of the car.

The invention further resides in certain novelties ofconstruction andarrangement of parts such as will be more particularly pointed out inthis specification.

In the drawings forming a part of this specification, Figure 1 is avertical, transverse,sectional view taken through a portion of a W typehopper car illustrating my improvements in connection therewith. Fig. 2is a side elevational view of a portion of the car, illustrated inFig.1, showmgthe discharge doors in fully closed posltion. Fig. 3 isaview taken on a line corresponding substantially to line 3--3 of Fig. 2.Fig.

Fig. 6 is a side elevational view of atwin hopper car showing another embodiment of my improvement inconnection therewith. Fig. 7 is a vertical, transverse, sect1onalv1ew,corresponding substantially to the section line 7-7 of Fig. 6. Fig. 8 isa fragmentary view of a discharge door and latch of the type illustratedin Fig. 6 showing a further modified form of construction. And Fig. 9 isa transverse, vertical, sectional View, corresponding substantially tothe section line 9-9 of Fig. 8.

Referring first to the construction illustrated in Figures 1 to 5,inclusive, 10 denotes one of the side walls of the car; 11 one of i thecenter sills; 12 the longitudinally extending ridge sheet over thecenter sills: 13 the transversely extending ridge sheet between the setsof hoppers: 14 one of the-hopper bottom sheets sloped downwardly fromthe end of the car towards-the center; 15 an inner hopper side sheet.and 16 an outer hopper side sheet, the latter being sloped downwardlyand inwardly towards the center line of the car. As will be understoodby those skilled in the art, there a e f l h pp r similar to the oneillustrated, two on each side of the center sill, and arranged in pairsextending transversely of the car. 1

Each hopper side sheet 16 is suitably flanged along the edge adjacentthe discharge opening, as indicated at 17 and 18,

to provide the necessary strength, and the lower edge of the bottomsheet 14 is reinforced by a transversely extending angle iron. 19secured to the underside thereof. Each hopper discharge opening isadapted. to be closed by a sheet metal door, 20. The doors 20 are hingedalong their upper edges to swing about axes extending transversely ofthe car, and each door is reinforced at the top and side edges byflanges 21. In the arrangement shown,each door 20 is hinged to brackets22, which are riveted to the trans.- versely extending ridge sheet 13,which is re inforced by means of angle 23.

Secured to each transversely alined pair of doors 20, adjacent the freeedges thereof and parallel thereto, is a connecting beam 24;commercially known as a door-spreader section. The beam 24 is preferablyin the form of a rolled channel shape member, comprising a pair of webs2525 united by means of a centralportion 26, and axp'air of flanges27-27 projecting outwardly from the extremities of the webs, the centralportion 26 and the flanges 27 being formed of a greater thickness ofmetal than the web portions 25. The spreader is secured to the door 20by means of rivets 28 passing throughthe flanges 27 and through the doorplate.

Secured to the opposite ends of the beam 24 are flanged extensions A,each preferably in the form of a plate pressed into shape to permit thesame to be secured to the beam in two different planes. The extensionmay be formed, as best shown in Figures 1, 4 and 5,

withflanges 29 and 30, at right angles to each other, the flange 29being secured to one of the web portions 25 of the beam and flange 30being secured to the central porga e the aforesaid extension A tosecln'elv ho d the door in closed position.

The latch B is pivoted on a bracket C which is secured to the car body,and a cam D cooperates with the latch B, as hereinafter specificallydescribed.

Heretofore it has been customary to dis pose the extension on the beammember to one side of the center of gravity thereof,

whereby the main line of force which passes through the latch pivot andthe door exerts a turning movement on the beam, tending to twist thebeam on its axis." The tendency to twist the beam is furtheraccen- 1tuated by the operation of swinging the door to closed position, itbeing customary to provide the extension with a perforation as indicatedat 33 adapted to receive a bolt 34 or a bar 35, by means of which thedoor is op- .Zu crated, the bolt or bar being passed through the openingand depressed in the directions indicated by the arrows 36 and 37respectively, swinging the door to closed position. These defects areremediedin the construc- 2 tion hereinshown, by deflecting the Web 38 ofthe extension A from one side of the beam to a position centrallythereof. This is accomplished by forming an offset 39 in the web of theextension, said offset extending at nn angle between the flange 29 andweb 38 of the channel shaped portion of the exten-- sion A. The curvedflange 31, constituting the latch engaging seat, is spaced from theouter surface of the door a greater distance than the flange 30, inorder to provide for proper clearance for the flange 31 as the samepasses under the flanged portion 21 of the door, wall 40 connecting theflanges 30 and 31 extending at an angle between the to same. Aperforation 41 is provided in the web 38 within which the latch may dropto retain the door in a nearly closed position,

as shown in Fig. 4:.

The brackets C rest upon and fit against an the angle irons 19, thelatter being extended outwardly beyond the sloping side walls 16 of thehop er, thus providing supporting ledges for t 1e brackets, it beingunderstood that I employ a bracket and latch at each side of the car,only one side, however, be ing shown in the drawing; Each bracket C ispreferablyin the form of a casting, having an inner wall 42 lyingagainst the sloping side sheet 16, and is secured to the lat- 5 1 ter bymeans of a rivet 43. The bracket casting C is also provided with anouter wall 44 disposed in a plane substantially parallel to the sloping.hopper side wall 16 and is spaced a short distance therefrom. The inherand outer walls 42 and 4-4 areconnected by a transversely extending wall45, and a wall 46 parallel with and secured to the cutstanding flangeofthe angle iron, 19, bymeans of a rivet 46. In addition the bracket isformed with a downwardly extending flange d7 secured to the dependingflange of the angle iron 19 by means of a rivet as.

- The latch member B is pivotally mounted 'on the bracket casting C bymeans of a pivot 49, and is adapted to swing in a plane substantiallyparallel with the slope of the car side. Lateral outward movement of thesaid latch member is prevented by means of a flange 50 formed on'theouter wall 44: of the casting C, and inward lateral movement thereof isprevented by means of the race 51 constituting the end wallet a boss 52extending outwardly from the inner wall, 46'

iron 19 with the hopper side wall, at the lower corner of the hopper,thereby prevent ing the hopper side sheet from tearing out at thispoint.

The locking cam D is pivotally supported between the outer wall M of thebracket C and the sloping hopper side wall 16 on a rivet or pin 54,which not only acts as'a pivot for the cam D but also serves to securethe bracket C to the hopper sheet. The cam D is of Well known form, andengages with a curved surface 55 formed on the latch member B. A ferrule56,preferably formed of a section of commercial pipe, is interposedbetween the sloping hopper side wall 16 and the cam D, therebymalntaining the latter in alignment with the latch B;

The outer end of the latch B is beveled as indicated at 57 so as toactas a guide tov lift the latch when the doors are moved to closedpositio u' said beveled end 57 being enga ed by the extension A, as willbe evident, tie latch drop ing into locking position under gravity, W enthe'curved flange 31 on the. extension A has passed beyond the I lookingface 32 of the latch B.

In the embodiment of the invention shown in Figs. 6 and 7, transverselyextending twin doors 110-410 are employed, pivoted to swing abouttransversely extending axes. The free edges of the pair of doors meet,and extending along the underside of each door, near its free edge, andparallel thereto, is the bracing beam 111 ofsubstantially U-shape crosssection comprising flanges 112 extending outwardly, from the upperextremities of a pair of webs 113, and a horizontally extending section114 connecting the lower. extremities. of the webs. In Figs. 6 and 7 ofthe drawing, 115 denotes one of the outer sidewalls of the car; 116 oneof the center sills; 116 the longitudinally extending inner walls of oneof the hoppers; 116 a bracket connecting the inner wall with the'centersill 116;

117 the transversely extending ridge-sheets;

- 118the door hingebutts; and 119 outwardly .and downwardly bentreinforcing plates secured ,to the outer side walls of the car. As willbe understood by those skilled in the art, only one-half of the car isshown in A Figs. 6 and-7, there being another similar formed upwardlyand merging with a flat portion, as indicated at 121, substantially inline'with, or in the same-plane as the body or main portion of the door,to, clear the beam 111 extending from one door-to the other. 7

" To hold the doors in closed position, there r is provided at each endof the beam 111 an extension E with which is adapted to cooperate'alatch F. The extension E is in the form of a metal plate of angularcross section, including a pair of flanges 122 and123 by which it issecured to the beam 111. The

extension E projects outwardly beyond the flange 120 of the door, theflange being cut away asindicated at 124 to permit of said ex- [iiitension projecting therethrough. The overhanging portion of theextension is prefer ably of channel form, comprising a web 125, an n gper flange 126 and a lower flange 127,

the atter being curved to correspond sub-,

stantially with the curvature of the shoulder 128 formed on the latch F.c

The latch F'is pivotally mounted in the bracket G- and is adapted to-belockedthereto by means of theloeking cam H.

The bracket G, preferably in the form of a casting, is provided with amain backwall or web 128, which, when the bracket is in position, bearsagainst and is secured to the side wall structure of the car by a seriesof rivets 129-129. To provide a housing and also q to prevent outwardmovement and bending of the latch and locking cam, the bracket G isformed with an outer wall or web 130, united to the main wall or web 128by means of transverse flanges 131 and 132.

The latch '13, and locking cam H, are housed between the out-er wall orweb 128 and an intermediate-wall 133 which extends from the transverseflange 131 to the transverse flange 1,32, and is spaced from theretaining wall 128 a sufficient distance to properly space the latchfrom the side wall of the car to clear projecting ortions of the carstructure. Said interme iate wall 133is'extended a distance downwardlybelow the transverse flanges 131 and 132 for the purpose of preventinginward bending of the atch F. Swinging movement ofthe latch F in aclosing or operative direction is limited by a transverse flange 134projecting from the transverse flange 131. The swinging movement of thecam H to its inoperative position, is likewise limited by the sameengaging the transverse flange 132.

As it is customary to swing the door to closed position by directapplication of the forces to the extensions E, great stability isrequired for these extensions both in regard to the strength of the sameand in the method of their attachment to thebeams. It is the usualpractice to provide the door extensions F with which the latches engage,with perforations to receive an instrument by which the doors are swungto closed position. One manner of accomplishing this result is toprovide the extensions E which project outwardly beyond the latch leverswith perforations 135 through which a bar or bolt 136 ma be insertedin'the manner shown in Fig. 6 or the purpose of swinging the doors toclosed position. Another manner of accomplishing this result is toprovide the web of the extension E with a perforation 137 through whicha bar 138 is passed, with the free end thereof engaging an abutment 139which may be formed on the door itself or on a portion of the carstructure. The operation of levering the doors to closed positionobviously creates a turning movement on the extensions and on the beams,which together with the strain imposed thereon due to the load from thedoors tends to distort and loosen the parts, and therefore, a rigidconstruction, such as that shown herein, is of great importance. v

With the form of latch lever illustrated herewith it is comparatively aneasy matter to swing, the doors on one side of the car to a closedposition, but it frequently happens Ion that the closing of the door onthe other side calls for some means of levering the doors dispo:edbetween the doors of each pair, the

plate 140 being provided with a cperforation 141 through which a bar maybe inserted for the purpose of levering the doors to a position whichwill enable the latch levers to swing into position under the extensionsE.

In FigsJS and 9 is illustrated a construction in all respects similar tothat shown in Figs. 6 and 7, with the exception that the reinforcingbeam 210 is secured to the door 211 by means of a connecting portionformed integral with the extension K and extending between the webs ofthebeam and that the extension K is of channel shape throughout toclosed position, due to 'thesame having lit) the length'thereof,Theextension K is se-. I

The extension is oflret'in a similar manner,

and for a purpose similar to that described in connection with Figs; 113072111611181.176, the

web portion 212 being disposed substantially in alignment with thecenter of the beam 210.
